Lightroom 5.2RC Screen Flicker in Library Grid Mode

Question

Hi,
Having a screen flicker problem since 5.cRC came out, but only in Library/Grid mode when scrolling or selecting from the grid. But only when there are more images than can fit on one page in the grid. 
Seems to use an unusually low amount of memory with nothing else running on the system.

Answer 1

I've been having the exact same problem with Lightroom 5.2.  I also have an Nvidia card, a GeForce GT 610, and driver version 327.23.  One additional part of the problem is that I can hear almost constant disk access when in grid view mode in the library module.  That seems to be related to Lightroom refreshing the display as I scroll down through the images.  On newly imported images, it takes about two seconds for each thumbnail to just display the keyword symbol in the lower right corner.  After the first time scrolling through all the images, it goes a bit faster.  Even then, CPU usage goes up to 80% just by selecting a new group of files.
It almost seems like something is making it take a long time to build each thumbnail and sync all the information that's associated with that thumbnail before it will let you do any other work with it.  I don't think it's really associated with the dislay driver.  I never had this problem with LR 4.4, it's just since I upgraded.  I also never had an ealier version of LR 5; I went right to 5.2 from 4.4.
